Follow-up Comment #3, bug #55780 (project octave):

Would be nice to know why there was a special implementation for the cubic
interpolation. This method already existed in core's interp2 back in 2006 when
imremap was written. It may be working around a bug in core or maybe it's done
for performance.

Anyway, we don't know why it was done so I guess it's fine to remove if it
fixes a problem now. Can you add a minimal test case so that it will fail if
someone tries to revert this in the future?
